I think this really depends whether you get your main income from it, or only to have extra bucks. I started out just a month ago because I needed extra money for this vacation I'll be having, now I'm really hooked in it. I don't think it's possible to have it as a real career for me, because well, I didn't work my butt off through nursing school, only not to practice as one. Despite that, I believe that making it as a career is not bad idea. There are quite a few who preferred this than their day jobs because well, sometimes you can earn more here, and you get to choose where and when you do your job. That kind of freedom is just not possible in other type of work. If this continues to go well for me, I might spend more time doing it, but it will still be more like a hobby than a job on my part.
